Local Flap Reconstructions in Oral Cavity Defects: An Insight from 104 Cases

Abstract

Background: Resection of oral cavity carcinoma often leads to complex defects causing functional and aesthetic morbidity. Providing optimum reconstruction with free flaps becomes challenging in a high-volume center setting with constrained resources. Hence, understanding the local flap technique for reconstructing oral cancer defects is prudent. Materials and Methods: This study is a retrospective analysis of prospectively operated cases of oral cavity resections which were subsequently reconstructed using local flaps from 2019 to 2022. Patients who underwent reconstruction with either melolabial flap, islanded facial artery myomucosal (FAMM) flap, submental flap, supraclavicular artery island (SAI) flap, infrahyoid flap, or platysma myocutaneous flap (PMF) were included in this analysis. Eligible patients were followed up to evaluate functional outcomes like oral feeding and to analyze the Performance Status Scale for Head and Neck Cancer. Results: The study included 104 patients. The tongue was the most common subsite, resulting in most hemiglossectomy defects, which were reconstructed using the melolabial flap procedure. Buccal mucosa defects in our series were reconstructed using the supraclavicular flap, whereas the submental flap procedure was the choice for lower lip-commissure defects. Complications such as partial and total flap loss, deep neck infection, and donor site complications like infection and gaping, oral cutaneous fistula, parotid fistula, and seroma were analyzed; the supraclavicular flap presented with a majority of complications. Conclusion: Local flaps are an alternative to free flap reconstruction in select cases with optimum functional outcomes and minimal donor site morbidity. This article comprehensively reviews the surgical steps for various local flap procedures in oral cancer defects.
